For chin augmentation, a small incision is made just beneath the chin. The surgeon prefers this incision to intraoral incisions because it offers more precise implant placement and allows exact re-approximation of the chin muscles. Intraoral incisions have been associated with chin contour irregularities from improper muscle healing. For cheek augmentation, a small incision is made inside of the upper lip. This implant is then inserted through the incision and positioned, and the incision is then closed.
